UNITED STATES ISAIAH C. SOUDDER, OF NEW YORK, N. Y.

VEHICLE-WHEEL.

Specmcation of Letters Patent.

Patented Sept. 22, 1908.

Application filed February 16, 1907. Serial No. 357,637.

a, a 1 a resident of Be it known that I, IsAIh' I citizen of the United States,

the city of New York, borough of Manhattan,

whereby the latter may be readily attached or detached while inflated.

The object of the invention is to provide a detachable rim adapted to support and carry an inflated tire, and to provide means whereby this rim may be quickly and easily attached in its place without the necessity for thelemployment of any specially-constructed too s.

The invention consists in certain features of construction and combinationof parts, all of which will be fully set forth hereinafter and particularly pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures, in which Figure 1 is a side elevation of a' vehicle wheel provided with my improved tire securing means, a portion of said wheel being broken away; Fig. 2 is a plan view of said wheel, a portion of the tire being broken away; Fig. 3 is a transverse section, said section being taken on the line 33 of Fig. 1 Fig. 4 is a partial transverse section through the valve stem, said section being taken on the line 44 of Fig. 1; Fig. 5 is a detail perspective view of the inner locking ring adj acent the opening for the valve stem Fig. 6 is a perspective view of a portion of one of the locking rings; and Fig. 7 is a perspective view of a portion of the two clamping rings, 7

showing the means for securing the same toether.

D My improved device is ada ted for use in connection with any form 0 vehicle wheel having a felly 10 supported by spokes 11 of any suitable character and connected to a The outer surface of the felly-1O is preferably smooth and provided with a metallic band 13 of a-width substantially equal to the width of the felly and having the portions thereof adjacent the outer edges tapered so as to present inclined faces the base flanges.

14. This metallic band is secured in place in any suitable manner and carries locking bolts 15 extendin inward through the felly at intervals, as il ustrated in Figs. 1 and 3.

In connection with the wheel having the v felly and metallic band above described, I employ a pneumatic tire of the ordinary form of construction and having an inner tube 16 and an outer shoe 17. The latter is provided with outwardly extending base flanges 18, which on the ordinary vehicle wheel are held within grooves in the felly or rim. In my improved construction, I provide two

clamping rings

19, 19 having means for securing the same together, and each having its outer edge curved upward and inward to inclose the base flanges of the shoe. The

flat main portion of each clamping ring is adapted to extend across the surface of the base flanges of the shoe and meet along the center line. The -meeting edges are preferably beveled so as to overlap as indicated in Fig. 7, and at-in'tervals along the length of these clamping rings means are provided for rigidly securing the same together. These means as indicated in Figs. 2 and 7, comprise locking keys 20, each of which is of substantially the same thickness as the

clamping rings

19 and 19*, and is adapted to fit within an opening in each of said rings. These keys are each preferably provided with a rectangular center portion and enlarged or dove tailed end portions, whereby when the key is inserted Within oppositely-disposed openings in the meeting edges of the clamping rings, the latter are positivelyprevented from spreading apart or moving in relation to each other, except in a radial direction in respect to the wheel. Each of the keys 20 is preferably cut away to form recesses 21 adjacent each end, whereby a pointed tool may be readily inserted to draw the key out of its place when 7 the rim is detached fromthe wheel. Each key is also preferably provided with inwardly-extending divergent flanges 22 which may be constructed as illustrated in Fig. 7.

These flanges are preferably formed of a piece of thin spring steel having its center or intermediate portion riveted or soldered to the intermediate portion of the locking key.

In connection with the arts above described,- I emplo an inner locking ring 23, preferably ihom oidal in cross section, and

1ts opposite beveled sides adapted to contact with the inner surfaces of the shoe adjacent The inner or widest surface of the locking ring is providedwith a cover or lining 24 of leather or other suitable material, which latter contacts with the sur face of the inner tube 16. r The outer or narrowest side of 'the locking ring preferably lies between the base flanges of the shoe and contacts with the keys 20 and the meeting edges of the

clamping rings

19, 19. This locking ring is preferably formed of steel, although it is evident that any other suitable material may be employed.

In assembling the tire and detachable rim the inner tube is placed within the shoe and the locking ring 23 inserted between the base flanges 18. This locking ring 23 is provided with a radial opening 25-for the passage of the valve stem 26, as is also the leather lining stri 24. The locking ring is preferably severe adjacent this 0 ening, whereby the ring may be more readi y inserted in place, and the lining 24 overlaps the joint in the ring and is itself out at a oint adjacent thereto, as clearlyindicated in ig.5. Having placed the locking ring 23 between the base flanges of the shoe, the two

clamping rings

19, 19" are placed in position with their outer curved ortions inclosing the outer surfaces of the ase flanges and their inner meeting edges lying in the same plane. The \divergent flanges 22 of the locking keys are then forced toward each other until they lie substantially parallel and theends are then inserted between the base flanges of the shoe and the locking ring 23, as indicated in Fig. 3. The outward spring movement of these flanges causes them to travel inward and to draw the locking key into position. The tire is then inflated and all of the parts become rigidly locked in position. The harder the tire is inflated, the greater will be the outward pressure upon the ring 23 and the tighter will be the clamping action against the flanges 22, whereby the locking keys 20.are prevented from accidental or intentional removal.

To ermit the above assembling of the detacha le rim and the remainder of the wheel,

. I construct the

clamping rings

19, 19 with an inner diameter shghtly greater than the outer diameter of the metallic band 13, whereby a thin annular space, preferably about one-eighth of an inch in width, is left when the tire and rim is placed about the metallic band 13. This permits the portion of the tire and rim carrying the valve stem 26 to be placed adjacent the felly and metallic band, while the main ortion of the detachable rim lies at an ang e to the plane of the wheel and whereby the valve stem may be passed through the opening provided therefor in the felly as the opposite side of the tireand rim is moved into engagement with'its corresponding portion of the felly and metallic band. 1

For securing the detachable" rim to. the wheel, I preferably provide two

locking rings

27, 27 having inner wedge-shaped edges adapted for insertion between the metallic band 13 and the clamping rings of the detachable rim. These locking rings are severed diagonally as indicated in Fig. 6, whereby the ends may be spread a slight distance apart to vary the diameter of the rings, and each ring is adapted to engage with the corresponding beveled face 14 of the metallic band. Upon placing the tire and detachable rim in position as above described and inserting the wedge-shaped locking rings in the annular space intermediate the two, the

rim and tire may be rigidly secured in place.

For forcing the locking rings into position and firmly holding them in place, I preferably provide a plurality of U-sh-aped clamps 28 readily movable in respect to the wheel and inclosing the felly to engage with the locking' rings 2727 at oppositely disposed points. Each clamp is preferably provided with a central hub portion 29 having a passage therethrough for one of the draw bolts 15, whereby upon tightening the nut 30, the clamp may be forced outward radially. The outer ends of the clamp are provided with beveled surfaces 31 which engage with corresponding beveled surfaces within recesses 32 of the clamping rings, whereby radial movement of the clamps force the locking rings toward each other and this inner movement of the latter causes them to become rigidly wedged between the metallic band 13 and the clamping rings to firmly, secure the tire vand its detachable rim in place.

Having thus described my invention, I claim as new and desire to secure by Letters Patent;

1. In combination, a vehicle wheel having an outer metallic band, a detachable rim, op-

ositely-disposed locking rings adapted for ocking said rimto said metallic band, and means for simultaneously forcing said lock- -ing rings into place, said means including a plurality of radially movable U -shaped I clam s.
